HTTP (Hypertext Transfer Protocol) uses TCP (Transmission Control Protocol) because it requires reliable, ordered delivery of data, ensuring that web pages load correctly and completely. TCP establishes a connection between the client and server, allowing for error checking and retransmission of lost packets. In contrast, DNS (Domain Name System) primarily uses UDP (User Datagram Protocol) because it is faster and more efficient for the quick, small queries typically involved in resolving domain names to IP addresses. UDP does not guarantee delivery or order, which is acceptable for the usually brief and stateless nature of DNS requests.
